My own brainf__k interpreter, written in node.
Uploaded this to NPM just for the sake of convenience.
Usage:
// CommonJS
const { run } = await import('bfscript');
// ESM
import { run } from 'bfscript';
run('>++++++++[<+++++++++>-]<.>++++[<+++++++>-]<+.+++++++..+++.>>++++++[<+++++++>-]<++.------------.>++++++[<+++++++++>-]<+.<.+++.------.--------.>>>++++[<++++++++>-]<+.');
